This invention pertains 'to a novel display device and to a method ofmaking the same.

The term display device as used herein refers to devices of thecharacter described hereinafter in greater detail, these devices beingadapted for use as display cards or holders for various articles such ascoins, stamps, combs,.belts and other articles. Moreover, the devices ofthis invention may be used not only for display purposes but may also beemployed as ameans of maintaining collections of articles in anattractive, orderly and permanent manner. For example, the displaydevices of this invention may be used to great Aadvantage as pages ofcollectors albums.

Although as stated hereinbefore the invention has many adaptations, inorder to facilitate understanding Ythe description given hereinafter`will be particularly directed to the use of the invention in connectionwith philately. y

`Heretofore stamp collectors have placed stamps in albums' by usingso-call'ed adhesive hinges. This method of mounting stamps in albums isnot satisfactorysince hinges occupy considerable space, therebyrendering the albums unnecessarily bulky, make it almost impossible toarrange stamps Without having them askew, and often cause injuries tothe stamps when it is necessary or desirable to move stamps from onepage to another or for other transfer purposes.

i The'display device of this invention, when used in a stamp album,comprises a double-faced sheet of-suilicient strength and rigidity toremain flat in actual use and be free from warping or curling due tochanges in temperature or humidity.

Each face of the display device is provided with a series of displayareas covered by strips ofv transparent material such as celluloseacetate, Cellophane or similar transparent or translucent material. Thisstrip material emerges from the body of the display device through verynarrow slits which delineate each display area. Preferably three slitsdelineate each display area, the transparent strip being unattached tothe face of the board along one edge so that stamps or other thinarticles (negatives, snap-shots, cards or the like) may be insertedunder the transparent strip. The method of forming the display cards ofthepresent invention causes the transparent strips to be maintainedunder tension and to be deformed in areas contiguous to the slitsthrough which the strip emerges so that objects placed beneath thetransparent strip are firmly held thereby but are Vreadily accessibleand visible to the observer or user.

- namely, the upper sheet 28 Other objects, uses,A advantages andadaptations of the invention'will become apparent to those skilled inthe art from the following detailed description of certain exemplaryforms of the present invention. Reference will be had tov the appendeddrawing, in which:

Fig. 1 is a plan View of a displaydevice made Y in accordance with thepresent invention.

Fig. 2 is an enlarged plan View of one portion of the display device.

- Fig. 3 is an enlarged transverse section taken along the plane III-IIIof Fig. 2, the lower portion of Fig. 3 being flared to more clearly showthe various members employed.

Fig. 4 is a planview of a portion of a modied form of display device.Fig. 5 is an enlarged transverse section taken along the plane V-V ofFig. 4, a coin held by the display device being shown in end elevation,the lower portion of this section showing the component parts separatedin order to facilitate understanding.

As shown in Fig. l, the display device, generally indicated at I0,comprises a plurality of display areasjII, I2, I3, I4 and I5, delineatediby the narrow marginal slits, such as the slits I6, I 'I and I8 of thearea II. Each display area iscov-Y ered by a strip of transparentmaterial, the upper edge of the transparent material at 2|, 22, 23, etc.When used .as a page of a stamp album, stamps may be inserted betweenthe face of the device and the transparent strips, the transparentstrips then holding the stamps in position as indicated in the twoexamples Vgiven at 25 and 2S.

Although Fig. l is a plan view of one face oi a displaydevice, thereverse side may be of identical structure.

The enlarged planview shown in Fig. 2 more clearly illustrates thearrangement of the parts, the transparent strip being indicated at 21.

The transverse section of Fig. 3 shows the reverse side of the displaydevice in a partially torn away'positlon for the `purpose of emphasizingthe construction. 1

It will be noted that the device III comprises two sheets of material ofappreciable thickness, and the lower sheet 29. When the display devicesare made -of cardboard, vit has been found desirable to employ aV beingindicated multi-ply board, and preferably a board of a thickness notthinner than a two-ply board. In ordinary practice, a four-ply board hasbeen found eminently suitable. Each of these sheets of material, such asthe sheet 28, is then die cut to provide narrow slits delineatingdisplay areas. The slits should dene not less than two margins of thedisplay area and as shown in Fig. 1, three slits I6, I1 and I8 delineatethe display area II. The narrow slit I1 is shown in Fig. 3. In makingthe display device, a strip of trans parent material is passed throughthe slits I6, I1

and I8, each strip extending over the display area and having its endsoverlying thev rear sur.- face of the sheet adjacent the slits. Forexample, in Fig. 3 the upper edge of the strip 21 is indicated at 2I butthe lower portion of the transparent strip 21 extends througlr the slitI1 and extends through the rear surface of sheetli!y adjacent the slit,as at 21. By referring to transparent strips, reference is m'ade totranslucent materials as well. Strips of Celluloid or Cellophane (eithertransparent and uncolored or colored, frosted or translucent) may beemployed. Certain synthetic materials in thin sheet form may be used togood advantage.

The companion sheet 23 is similarly provided with narrow slitsdelineating various display areas and similar strips of transparentmaterial are positioned over the display areas as, for example, thestrip 30. The two sheets 28 and 29 are then placed in back to backrelation with a sheet of pressure bonding material 3l positionedtherebetween. Preferably the pressure bonding material 3| is coextensivein area with the entire area of the sheets 28 and 29. The material 3Imay comprise a thin sheet of thermoplastic material or a cellulosic webcoated or impregnated with a pressure bonding substance, resin oroomposition. Thin sheets of paper saturated with shellac, plasticizersand other resins may be employed to good advantage. The entire assembly,including sheets 28 and 29, the transparent strips carried thereby andthe intervening layer of pressure bonded material 3|, is then subjectedto pressure and in somev instances to heat as well as pressure. Theamount of heat employed depends upon the character of the pressurebonded material used between the two sheets 28 and 29.

Materials requiring temperatures sufficiently high t0 discolor thetransparent materialsl21 and 30 should not be employed.

After the pressure has been removed, it will `be found that theintervening layer 3l is substantially indistinguishable as a separatelayer and has rmly bonded the sheets 28 and 29 together. Moreover, thepressure (and heat) has now caused the transparent stripsY 21 and 30 tobecome deformed in areas contiguous to the slits defining the displayareas. For example, the strip 21 has now been deformed so as to form acorner 32 where such strip entersrthe slit I1. The application ofpressure during the bonding and assembly has moreover placed the strip21 under tension so that it lies closely adjacent the outer surface ofthe sheet 28 and will not stretch or distort during prolonged use.

It will be noted that in the event a card, snapshot or stamp is insertedbeneath the strip 21, l

the lower part of the stamp will abut the deformed portion of the stripat the corner 32 and inasmuch as the strip 21 is under tension, thestamp, card or snap-shot will be firmly held between the sheet 28 andthe strip 21 so as not to be dislodged from its position. Moreover,since the sheet 28 is of appreciable thickness and is an inherentstructural portion of the finished display device, there are no loose orinsecure surfacing elements which may peal from the working surface ofthe display device.

The modification shown in Figs. 4 and 5 is particularly adapted for usewith objects of appreciable thickness, such for example, coins,metals,`buckles, straps, belts, articles of jewelry, and the like.Whereas the display device of Figs. 1, 2 and 3 had display areasdelineated by three narrow slits dening the boundaries of each displayarea, such slits being in intercommunica tion, each` display area of thedevice shown in Figs. 4 and 5 is delineated by only two slits, one ateach end, a narrow slit 4I! being indicated in Fig. 4, such slitconstituting one end of a display areaA covered by the transparent strip4I. The deviceitself is formed of two sheets of material 42 and 43, theslits delineating the margins of the display areas carried by each ofsuch sheets being substantially superimposed when the two sheets areplaced in back to back relation.

In addition, each display area may contain one or more cut-out portionsor apertures. Ifyfor example, the display area is to receive a pluralityof coins or metals, the sheet 42. within the boundaries of the displayarea 4I may be provided with circular apertures 44, 45, and the like.

Sheet 43 is provided with identical apertures,'as

Ysuch as end slit V4l), so as to extend onto the rear or back side ofthe sheet 42, as indicated at 4I A similar strip of transparent material41 is caused to extend over the display area of sheet 43 and the endportions of strip 41 pass through slits delineating the ends of suchdisplay area.

The two sheets 42 and 43 are then bound together by means of anintermediate layer or strip of pressure bonding material 48. Thetransparent strips 4I and 41 are placed under tension during thiscementing process and are firmly held over the display areas.

'In actual use, suitable coins may be placed beneath the free edges ofthe transparent strips, such as strip 4I, and slid into the pocketformed by the registering apertures of sheets 42 and 43 such as,forexample, the apertures 44 and 46 shown in Fig. 5. When so mounted,the coin, metal or other object is retained in position within thedisplay device but is clearly visible to ob- 'servers so that both thefront and reverse sides of a coin or metal may be examined withoutremoving it from the display device. When the display devices of thisinvention are employed in book form, 'as in collections of coins,stamps, or other objects, they may be provided with a hinged endportion, such as the portion 50 provided vwith perforations 5I, 52, andthe like, adapted to fit into a loose leaf binder or other bindingmeans. The portion 50 may be attached to the display device by means ofa flexible Webbing 53 cemented to the strip 50 and to the displaydevice, thereby permitting the display device to be freely moved andturned while held within a suitable binder, standard or the like.

Numerous modications and changes may be made in the form of theinvention as will be readily apparent to those skilled in the art. Allchanges and modications coming within the scope of the appended claimsare embraced thereby.
